SPECIFICATION forming part of Letters Application filed July 20, 1985.

To all whom it may concern:

Be it known. that I, WILLIAM B. COGSWELL,

of New York, a citizen of the United States, have invented certain new and useful Improvements in Bicarbonate Columns, of which the following is a specification, reference being bad to the accompanying drawings, in which- Figure 1 is a longitudinal vertical section of one of the horizontal segments of the column; Fig. 2, a top plan View of same, showing sec tions of construction at the ends of the piping system; Fig. 3, a plan view of the inner face of the pipe-heads; Fig. 4, an elevation of the column.

My invention relates to the manufacture of bicarbonates; and it consists in the construction of the apparatus, and not in the chemical portion of the process.

My object is to partially cool the liquid contents of the column or reduce their temperatu re, so that they leave the column cooler than by the ordinary process, where tubular cot umns are used without any cooling attachments.

It consists in the use of internal or partly internal and partly external coolingpipes, with the exterior internal surface of which the hot liquid comes into contact, and which pipes are kept as cool as possible by maintaining a flow of cold water through them, or by any other equivalent means.

I construct my column as follows:

A represents a section of the column, tubuare secured to the preceding and following sections in any ordinary manner, as the column is built up of successive superimposed sections until the desired height is reached.

B B are rectangular nozzles, formed integral with the body'ot' the column, opening outward and into the interior of the section, the openings being usually rectangular in form. These nozzles are located opposite to each other upon the periphery of the section, and usually in the same horizontal plane.

0 C are the flue-sheets, perforated, as at a, to receive the flue-pipes D D,-and also provided with holes to receive the bolts by which these sheets are secured to the outward flanges of the nozzles. The fines are set in these sheets in any ordinary manner.

Patent No. 362,938, dated May 17, 1887,

Serial No. 172,146. (No'model) E E are the covers, provided with the partitioirwalls b 1) upon E and (Z upon E, which walls stand out at right angles to the inner faces of the covers, and when placed in position form the chambers 1, 2, 3, 4, and 5.

F F are couplings for the inlet and exit pipes for the water or cooling mixture.

H H are couplings, which can be used when it is desired to couple by connecting-pipes the sections (two or more) of the column together, so that the water will flow from one section through another.

In Fig. 4 several sections are shown coupled together, and all taking the water from a single stand-pipe, m, e 0 representing the connecting pipes and a n the exit-pipes.

My invention is operated as follows: The water enters the chamber 1 through the coup ling F, passes thence through the flues transversely into the chamber 4, thence through the flues into the chamber 2, thence across into the chamber 5, and thence across into the chamber 3, from which it passes out through the coupling F. The drawings show the pipes D arranged in pairs; but they may be arranged singly, or in any other manner desired. By the use of these pipes the contents of the column are much reduced in temperature when they leave it, and the quantity of bicarbonatcs produced is largely increased by the quickening of the process.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is-

1. A bicarbonate column consisting of a series of superimposed sections, provided with transverse fines continuously connected, and having inlet-pipes opening into the lines and exit-pipes coupling the sections together, substantial] y as described.

2. A section for a bicarbonate column, consisting of a body, A, nozzles 13, llue-sheet O, tlues D, cover E, and inlet and exit couplings F F, constructed and operating together, substantially as described, for the purposes set forth.

In witness whereof I have hereunto set my hand this 5th day of January, 1885.
